I have used a lot of exchanges like Binance KUcoin BYbit Pancakerswap but the worst one is p2pb2b. this is a very worst exchange for me because when I use it, I always got lost because of its chart.
I received a Token from Giveaway but i see that this token only listed on p2pb2b exchange when i open this exchange then i see that kyc is mandatory for Deposit and Withdraw, i did it but still i cannot sell my token. So for trading i use Top exchange and for Temporary reason i use another low class exchange.
Some giveaway tokens and bounty tokens are listed in bad exchanges, yes, you can sell them but the volume is very low and they also demand a KYC. I'm thinking sometimes that these kinds of exchanges are only used by a fake project to show to the investors that the project is listed in an exchange and to let them feel that they are legit.
